Abstract: An electronic apparatus using a liquid crystal display device, a display control method used in the liquid crystal display device, and a non-transitory recording medium for storing a display control program, sets a region having a larger area of an information display region and a background region as a transmission region and a region having a smaller area as a shielding region. A tint change of the shielding region caused by a TN type liquid crystal and a light source for backlight is reduced, and thus, it is possible to make the tint change depending on the viewing direction unremarkable.

Abstract: An imaging unit generates image data of a video as a plurality of frame data that are continuous in a temporal order. An imaging control unit generates metadata indicating an imaging condition of the imaging unit in association with the frame data in a case in which the imaging condition is changed. An output control unit and an external output I/F add the metadata to the frame data and output the frame data to which the metadata is added as video data before demosaicing. In addition, in a case in which a data amount of the metadata associated with the frame data exceeds an addable data amount, the output control unit and the external output I/F add metadata selected based on a priority from among the metadata associated with the frame data to the frame data.
